Although they never impressed any critics with great lyrics, they pounded their message to their listeners with volume and histrionics. They didn't break new ground, but deserve their place as a seminal "Heavy Metal" artist. Great showmanship from Iain Paice, tight and very LOUD music, played by skilled and accomplished musicians, and real honest headbanging music made it into a case of "right place / right time" and they took that and ran with it. I like most of their work.
